SPARK-CATCHER.

SPECIFICATION forming part of Letters Patent No. 652,897, dated July 3, 1900.

Application filed April 27,1900.

To all whom it may concern.-

Be it known that I, NATHAN KEBSIINER, a citizen of the United States of America, and a resident of Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Spark- Catchers, of which the following is a specification.

My invention relates to an improved sparkarrester mechanism adapted particularly for use in connection with locomotive-boilers.

The invention is fully described in connection with the accompanying drawings and is specifically pointed out in the claim.

Figure 1' is a longitudinal sectional elevation of the smoke-box end of a locomotiveboiler, showing my improved spark-catcher mechanism applied thereto." Fig. 2 is a sectional plan view of the same, showing afull top view of the main portions of the spark mechanism.

A represents the forward end of the cylindrical shell of the boiler; a, the front fluesheet, through which the boiler-fines I) extend, and B the cylindrical smoke-box, connected to the boiler-shell and provided with a smokestack opening b located directly above the engine exhaust-pipe, (indicated by dotted lines 6 The forwardend b of the smokebox extends some distance beyond the stackopening, as is commonly the case in this class of boiler.

In order to prevent the free passage of the sparks which are carried through the boilerflues b to the stack, I provide a perforated partition in front of the flue-sheet, as is frequently done; but I specially form this partition and connections thereto for the purpose of satisfactorily disposing of these sparks, as I will now describe. For the upper portion D of this partition I preferably employ a wirenetting, as usual; but the lower portion B is formed of a metal sheet having two large openings d di'one on each side of the center line'of the boiler, with'which openings are connected conduit-pipes E and E, extending forwardly therefrom around the exhaust-pipe b and adjacent to the side walls of the smoke-box to the front portion of the latter, where their reduced ends 6 and e connect with opposite Serial No. 14,531. (No model.)

sides of a spark receptacle or box F, which is suitably carried in the forward end of the smoke-box. This receptacle is provided with a perforated wall f, adapted to permit the free passage of the heated air or gases drawn through the flues to the stack, but to prevent the escape of the sparks carried thereby, thus causing the latter toaccumulate in the receptacle F until they can be conveniently removed in any convenient manner-as, for instance,'by opening the lid or cover f, which is preferably hinged thereto and secured in closed position by any suitable means.

It will be evident that any sparks carried through the flues b and brought into contact with the partition D D will tend to collect at the bottom of the chamber d, formed between said partition and the face of the flue-sheet a; but it is also evident that any objectionable accumulation likely to obstruct the lower flues, as ordinarily, cannot occur, owing to the fact that the draft acting through the perforated receptacle F and the conduits or tubes E E carries the sparks promptly into said receptacle,where they are finally retained instead of discharging through the stack and can accumulate to a considerable amount without any interference whatever with. the free action of the draft through the lower as well as the upper boiler-fines.

What I claim is- The combination with a locomotive-boiler having a forwardly-extendin g smoke-box with smoke-stack outlet at the top thereof, of a spark-catcher mechanism in said box comprising a partition located in front of the flue-sheet of said boiler and arranged to form a spark-collecting chamber, exit-conduits extending from each side of said chamber below the center line of the boiler, and a sparkreceptacle connected to the forward ends of said conduits and having a perforated or screen wall and provision for emptying the same, substantially as set forth.

Signed by me at Reading, Pennsylvania,

this 25th day of April, A; D. 1900.
